this I2C IP is meant for automatic STOP, based on programmed number of bytes to be sent or receivede, not a user triggered STOP. So the state machiine needs to be reset in case we use this I2C mbed unitary API (start / byte_write / byte_read / stop).

This I2C IP is meant for automatic STOP, based on programmed number
of bytes to be sent or receivede, not a user triggered STOP.
So the state machiine needs to be reset in case we use this I2C mbed
unitary API (start / byte_write / byte_read / stop).
This PR allows to solve some remaining issues with i2c ci test shield on L4 / F3 / F7 boards.
